A balcony includes a balcony assembly and a structural post and outrigger system. The structural posts provide structural support for buildings and include the outriggers that extend substantially perpendicularly from the structural posts to a location where the balcony assembly will be installed. The outriggers include a tube or beam and an end plate on an end of the beam distal from the structural post. The balcony assembly includes at least one long beam, a platform, and a locking mechanism on an end of the long beam. The locking mechanism includes a channel for receiving and securing the end plate of the outrigger. The balcony assembly is secured to the outrigger using fasteners.
